Zen - AI Mental Health Companion

Developed an AI-powered mental health chatbot with emotion detection, RAG-based knowledge retrieval from 21 clinical psychology PDFs, and interactive wellness tools (breathing exercises, grounding prompts). Built embedding-based retrieval using FAISS + Sentence Transformers, grounding LLM responses in evidence-based clinical material. Orchestrated Meta-Llama-3-8B-Instruct via Hugging Face Inference API; reduced unsupported responses to ~5% using j-hartmann/emotion-english-distilroberta-base.
